Screenplay note

The screenplay by Donati and director Sollima was based on an original screenplay by Franco Solinas (Quien sabe?, Tepepa) and Fernando Morandi, which was situated on Corsica, but then transferred into a SW setting. In that course the screenplay was so much altered that (similar to Il Mercenario) Solinas was only named in the credits for the idea.

Synopsis

Jonathan Corbett (Lee van Cleef), a bounty hunter, is assigned to follow Cuchillo (Tomas Milian) who has allegedly committed a rape. A rich landowner encourages Corbett, who hopes to help Corbett stand for senator once he has succeeded in his quest. Corbett embarks on a manhunt through Texas and Mexico, staying on Cuchillo's tail. Corbett catches him, and Cuchillo escapes. During the course of the deadly hunt, Corbett's doubts about the manhunt grow. When the landowner shows up in Mexico to put an end to the business, the landowner confirms Corbett's suspicion. Something is amiss and only a showdown will suffice when everything comes to light.
